LAMP-BURNER.

1 Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed April 30, 1906. Serial No. 314.475.

To all whom it may concern:

Be it known that I, FRANK A.SCHUETZ, a citizen of the United States, anda resident of Chicago, county ofV Cook, and Stateof Illinois, haveinvented certain new and useful Improvements in Lamp-Burners, of whichthe following is a specification, and which are illustrated in theaccompanying drawings, forming a part thereof.

The invention relates to burners for that type of lamp used forsignaling purposes by railroads and commonly known as the longtime7burner, the lamp being expected to burn for several days withouttrimming or refilling.

The object of the invention is to provide a burner of this type capableof giving a strong flame and so guarding the flame that the danger ofits extinguishment by air-currents is greatly reduced.

The invention consists in the structure hereinafter described, and whichis illustrated in the accompanying drawings, in whichh Figure 1 is aplan view of the burner. Figs. 2 and 3 are vertical sections on thelines 2 2 and 3 3, respectively, of Fig. 1; and Fig. 4 is a plan view ofa detail of the construction separated from other parts.

The burner comprises a body portion l0, having a threaded neck forengagement with and a wick-tube 11, passing through and extending abovethe body, suitable fingers 12 being providedfor supporting and clampinga chimney. (Not shown.) A plate 13 is secured to the upper end of thewick-tube and extends laterally therefrom. This plate is apertured upondiametrically opposite sides of the wick-tube, as shown at 14 15, andfrom the inner ertures there rise flaring wings 16 17. Intermediate ofthe apertures 14 15 the plate is apertured, as shown at 18 19, and fromthe outer margins of these apertures rise a pair edges of these apl ofinwardly-inclined lips 20 21. As thus far described, the burner issimilar to the burner forming the' subject of my application for LettersPatent Serial No. 296,164.

From the outer edges of the plate 13 depends an annular skirt 22, whichterminates above the top of the body 10 and serves to steady the flameby directing all of the aircurrents upwardly, so that no cross-currentsor angular currents reach the flame, except such as are deflected uponit by the lips 2O and 2l. The skirt 22 gathers within itself a solidcolumn of air, which passes upwardly through the apertures in the plate13. The air passing through the ports 18 19 is inclined inwardly andsupplies the necessary oxygen for developing a strong flame. The airpassing up through the ports 14 15 provides a supplemental supply whichcombines with the carbon at the margins of the flame, and thus preventsthe development of smoke. These columns also sweep the inner surface ofthe chimney and protect it from smut.

I claim as my invention- 1. In a burner, in combination, a wicktube,flaring wings rising from opposite sides of the end of the tube, portedplates extending laterally from the end of the tube and intermediate ofthe wings, and an annular skirt depending from the plates and being openat the bottom.

2. In a burner, in combination, a wicktube, a plate extending laterallyfrom the tube end and downwardly flanged at its outer edge, andapertured through its upper face to form tongues, one pair of suchtongues being oppositely disposed and inclined upwardly and outwardly,and one pair thereof being oppositely disposed and inclined upwardly andinwardly.
